Fire sound, light and smoke detector fire hydrant connection problems

Now the equipment of each part of the fire alarm system is a bus system (if you don't understand what is the bus system, I hope you will check what is the bus system first), the fire hydrant you said is connected to the smoke detector, it means that there is a fire hydrant button in the fire hydrant box, the fire hydrant button is a kind of external equipment of the fire alarm system, which is used to start the fire hydrant water pump, and the separately designed 6 pipes are through 6 wires into the fire hydrant pump control cabinet, regardless of whether the bus is good or not, you can directly start the fire pump. The pipe connected to the smoke detector is used to wear the bus, and the bus is used for the communication between the fire alarm host and the external equipment of the fire alarm system, two, square twisted pair cables, but the requirements are flame retardant. The external equipment of the fire alarm system generally includes a series of equipment such as smoke detector, temperature sensor, hand report, sound and light, monitoring module, control module, fire hydrant button, combustible gas detector, etc.

These devices are all bus-based, so the tubes are all connected together.

The automatic alarm system is now a bus system, with a total of four buses, including 2 signal lines, 2 power lines, cigarette butts, warm heads, sound and light hand reports, fire hydrant buttons, and modules all need signal lines, as long as it is a circuit, they can be connected together. The fire hydrant wears a 6-point pipe alone, which is through the pump line, and the fire hydrant button now has a direct start pump.

Now the manufacturer's equipment is coded, fire hydrant button, hand report button, smoke detector and other lines are bus system, so a circuit of equipment must be connected together back to the host of the fire control room.

Do you say 6 wires? 2 start-up lines directly feed into the control cabinet of the pump room. 2. The root is connected to the smoke detector, and there is a premise that the input module must be added.

The module can report the address... As for the other 2; It is a 24V power cord drawn from the water pump room, because the fire hydrant button has an indicator light, and the light will not turn on without a power supply.

The two bus signal lines of sound and light alarms, hand alarms, smoke detectors, and fire hydrant buttons can be shared, but the connected equipment must be guaranteed to be in the same circuit, otherwise there will be heavy numbers and failures.

The signal line is completely common. Just remember that the total number of points you have connected to is not more than the standard of your device's product.

Hello! The fire protection system has a fire alarm host, a host can have several circuits, as long as the ones you mentioned above are in the same circuit, their signal lines can be shared.

Hope it helps!

As long as it is a device of the same circuit, the two buses of these devices can be shared.

The smoke detector will not sound, and the sound and light alarm will sound.

There are smoke detectors on each floor of the fire department, sound and light alarms, and how to connect the pump to the isolator.

First, the wiring method. Usually we use two buses, that is, signal lines (two) and power cables (two DC24V). The sound and light alarm has 4 wires, 2 signals and 2 power supplies.

The manual alarm button is generally 4 wires, 2 letter bucket numbers, and 2 **. The fire hydrant button usually has 6 wires, 2 signals, 2 power supplies, and 2 pumps. Just connect the two wires of the audible and visual alarm together.

Second, the installation method. The sound and light alarm is composed of a detector and an alarm control host, which is widely used in the petrochemical industry with toxic gases such as oil, gas, chemical industry, oil depot, etc., to detect the leakage of indoor and outdoor dangerous places, and is an important instrument to ensure production and personal safety. When there is a toxic gas in the measured place, the detector converts the gas signal into a voltage signal or a current signal and transmits it to the alarm instrument, and the instrument displays the percentage concentration value of the lower limit of the toxic gas**.

When the concentration of toxic gas exceeds the alarm set value, the sound and light alarm signal prompts, and the personnel on duty take safety measures in time to avoid the occurrence of ignition and explosion accidents. 1 Precautions for application: Once the fixed installation of the sound and light alarm is in place, its position is not easy to change, and the following points should be considered in the specific application. (1) Find out what possible leakage points of the device to be monitored, analyze their leakage pressure, direction and other factors, and draw a probe location distribution map, according to the severity of the leakage, divided into three levels.

2) According to the specific factors such as the direction of the air flow and the wind direction of the place, judge the leakage direction of the toxic gas when a large number of empty mackerel leaks occur.
